Name guide: My first name is Ben Lee and my last name is Volk. But it's OK, nobody gets it right the first time.
If you call me Ben, I will answer without correcting you and not make a big deal out of it. If you spell it as Ben Lee Volk in your *.bib file (with this exact order and capitalization),
BibTeX will correctly infer the first and last names. To read a whole lot more about how BibTeX processes names, see
this paper,
which is also likely to fulfill your lifelong dream of reading a document that contains the phrase "First von Last".
